CHIIVINEY-TOP.

SPECIFICATION forming part of Letters Patent No. 386,010, dated July 10, 1888.

Application filed September 25, 1886. Serial lNo. 2143489. (No model.)

To all wiz/m, t may concern:

Be it known that I, ALMANZON HEREN- DEEN, of Putnam, in the county of `Windham and State of Connecticut, have invented certain new and useful Improvements in Chimney-Tops, of which the following is a full, clear, and exact description,whereby any one skilled in the art can make and use the same.

The obj ect of my improvement is to utilize the features of invention shown and described in United States Letters Patent granted to nie July 6, 1886, No. 344,832, andto provide such a device with means for adapting it to chimneys of different sizes, to provide it with means for increasing the draft, and also to shield the chimney-mouth from storms; and

to this end my improvement consists in a chimney-cap consisting of a hollow casing made in sections, so that it is adjustable both vertically and laterally.

It further consists in the improved means for inducing a draft in the chimney, and, still further, in the improved storm cap or cover, and in details of the parts, as in ore particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a viewfer to make the protector of cast metal, as

iron, the outer casing, d, being of a size somewhat larger than the outside dimensions of the chimney, while the Hue-extension c is a tubular casting of about the inside dimensions of the chimney. The casing d is made in a number of sections sup erposed vertically, the lower section having a socket, d', formed between downward-extending flanges on the bottom of.

the casing, the outer flange extending down the outer side of the chimney and the inner flange extending downward within the chimney, so as to embrace in this annular socket one or more o f the upper courses of brick when the casing is placed upon the top of the chimney. QIn the upper part of this base there is a flange, between the sides of which is a flueopening, d5, and a socket, d4, in this upper part is adapted to receive the lower end of a section of the flue-extension e. In order to protect the space between the outer walls of the casing d and the walls of the flue-extension e, a cover, j', is provided, that iits upon the top of the casing, and has a sloping upper surface, as shown in the drawings. This cover and the several parts of the protector are held together by any suitable means, as bolts or screws. The air in the chamber or space between the outer casing and the flue-extension is heated by the rising of hot air within the chimney, and slots c are cut through the walls of the flue-extension near its upperpart and opening into the chamber. Other openings are formed in the outer wall of the casing, both to lighten it and to permit a circulation of air that when heated will flow through the openin g e and increase the upward draft in the flue b.

In order to adapt this chimney-top to more than one size of chimney, it is made in sections, the several parts having verticallymeeting faces and projecting lugs with edges undercut on the opposite sides, so that a clamp, 7L, with a dovetailed and tapered groove may be slipped upon these lugs and the several parts of any one section clamped together. Each of the sections consists of a corner-piece and a certain part of the straight side, the filling-pieces being made of straight sections of a length equal to about a brick or half a brick in length. These corner pieces and lling-pieces being provided, it is easyto iit up a complete chimney-top embodying my im'- provements and of any desirable size. The casing is made in separate parts, vertically as well as laterally, so that a top of any desired height may be made up by using two or more of such sections and fitting them together.

flue, in which uprights may be secured, and these uprights are slotted to receive a clamping-bolt', that passes also through a slot in the lugs j of a storm-cap,j, that more or less completely covers the flue, and is suspended over it at any desired height within the length of l Sockets t' are provided on the inside of the- IOO the slot in. the uprights and the lugs, the cap being secured at the desired height by tightening the cla1np-screwsl claim as my improvementl. The herein-described chimney-top, consisting, essentially, of metallic sections capable of being superposed one upon another, each section being formed `in two or more parts, and spacing-clamps, the edges of which interlock with the edges ol' the part sections to bin d the part sections together, whereby the seetion may be expanded to iit chimneys of diti'erent sizes, substantially as set forth.

2. The herein-described chimney-top, consisting, essentially, of sections formed of cast metal capable of being superposed one upon another, each section bein g formed in two or more parts, and spacing-clan11' s to interlock with and bind together the edges of the part sections, substantially as set forth.

f3. A chimney-top section formed in two or more parts, the edges of the parts being dovetailed, and spacing clamps provided with dovetailed edges to engage the edges of the said parts, substantially as set forth.

4. The combination, with a chimney-top, c, of a stor1n-cap, j, having depending arms or lugs j', provided with Verticall felongated slots, slotted lugs attached to the chimney-top in position to correspond with the lugs j', and clamping-bolts to lock the lugs j to the lugs on the chimney-top, whereby the storni-cap is secured in the desired Vertical adjustment, substantiz'tlly as set forth..

5. ln a chimney-top, the combination, with `an interior `flue composed of sections capable oi' beine1 superposed one upon. another, the sections each consisting ot two or more parts united by spaci 11g-sections, of an exterior flue :formed by several sections capable of superposition one upon another, each section consistin g of two or more parts united by spacingsections, the sections of the exterior fine bein provided with draftfopenings and the sections of the interior line beingprovidedwith draft` openings, substantially as set forth.
